ROOF-SCAFFOLD BRACKET.

To all whom it may concern I Be it known'tha't we, Crninnns S. l VINN and CLARENCE Af'l VALL, citizens of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois,

have invented certain new anduseful Im-,

provements in Roof-Scaffold Brackets, of which the following is a specification.

This invention relates in general to'roof scaffolds and more particularly tofbrackets adapted to support a scaffold orstaging such as is used when shingling, repairing or simple in its design and structure so that it I will be light in weight and inexpensive to manufacture, and WlllCli will be capable of various adjustments to permit its use onroofs of many different styles and pitches.

Another object of our invention is to provide a novel means for maintaining the bracket in its operativeposition and for permitting it to be readily adjusted to differentelevations upon the roof.

A further object is to provide means for connecting thebracket supporting means to the side of a gable roof opposite to that on which it is located, this being desirable when the ridge-boards are not yet placed in position and when working on hip-roofs.

A further object is to construct a bracket of two triangular sections pivotally connected at one angle corner and with one section arranged within the other and so proportioned that when the outer section rests upon a roof of a relatively steep incline with its pivoted angle corner highest upon the roof, the entireinner' section when adjusted to a horizontal position will be disposed directly above and in vertical alinement with the lower section, so as to prevent tipping of the bracket out of its operative position. Referring to the drawings: Figure l is a view in perspective of one of our improved scaffold brackets, showing it mounted upon a gable-roof. Fig. 2 is a viewin perspective of the bracket in folded or collapsed position in which it occupies but little spaceand may be conveniently transported orstored.

'Roof brackets of the general character to which our invention pertains are generally used in pairs to support a scaffold or staging upon an inclined roof, the brackets being I located at opposite ends of thestaging.

Brackets embodying our invention are all similar in structure and each has separate means for maintaining it in operative posit on and for adjusting it to different eleva tions upon the roof; Each bracket is formed of two metal lengths bent into trian gular shaped sections 6 and 7 whose endsterminate at one angle of the' triangles and are connected by a bolt 8 passing therethrough so as to pivotally connect the triangular sections and permit relative movement thereof. Section 7 forms a base and is adapted to be positioned with its pivot end section 6 may be swung to a horizontal posiits top face The section 6 is arranged highest uponan inclined roof, so that the within the section 7 so as'to be movable into the same plane thereof and is shorter in length from its pivot than section 7 as'is clearly shown in Fig. 2, this difference in length of the sections permitting, when the bracket is mounted'on a roof of a maximum incline, the outer end of section 6 to be maintained substantially in vertical aline-f mentwith the outer end of section 7 thereby insuring against overbalancing of the bracket. Braces 11 pivoted at one end to opposite sides of section 7' have their, outer ends adj ustably connected to the correspondmg side portions of section 6 for supporting the same in ascaffold carrying position;

The braces are connected with the section 6 by means of bolts 12 adapted to be in serted through the requisite holes 13 in the braces, which will position the outer endof the section 6 at the proper height.

The bracket is supported and maintained in 'position'by a chain or cable attached to an upper portion of the roof. The support mg connection includes a member carried by the bracket, to "which means one end of" the chain or cable is permanently attached and to which the cable may be attached at different points intermediate its ends to permit ready adjustment of the bracket to different elevations on the roof. The member as shown is bent upon itself to form a pivroof, in practice the engagement being either with a ridge-board 18 as shown in Fig. 1 or by engaging the hook with a roof board (not shown). before-the roof is shingled. V

The chain supports for the brackets are of such length that when theliooks 17 are engaged with a ridgeboard the brackets are iiiaiiitained ata relatively low position on an ordinary roof. lVhen in sliingling or re pairing arooI it becomes desirable to move the brackets successively to higher elevations on thereof the brackets are moved upward and inaintaiiied in their new positions by engaging the, chainportions which are adjacent thehrackets-withthe hooks-l6v thereof, in the; niannenshown inFigs. l and 3, thus permitting the brackets to be read ly positioned at any intermediate eleyation on thereof within the limits of the chain lengths l5.

When shinglinga roof it is customary not to mount the ridgeboardsin position until the sh ngl ng has. been completed, therefore a dl fi'elent means for. connecting the brack etswiththeroof is necessary. Such a means We have shown in Fig 5 and illustrated its application in Fig. 4. This means comprises 1 a separate chain or cable length 19 having anordinary hook 20 at one end adapted to beengaged the chain section 15, and a peculiarly shaped hook; 21 at its opposite end, which hook-has a relatively wide mouth,

and holding face preferably formed by bending suitably shaped strip of sheet metal upon itself. This wide-faced hook is adapted to; engage a shingle in an effective opposite. side of the roof.

It will be manifest that the brackets when connected to the roof through means of the auxiliary chain lengths may be adjusted to diflerent elevations in a nannersimilar to that above described. Also when the chain lengths 15 are not long enough for a particular roof, the hooks 17 of said chains may be hooked into chains 19 adjacent the hooks 21', and the hooks 20 of the latter chains en- The tions on a roof.

gaged with the roof, thus permitting the staging to be positioned at the lower portion of the roof. WV hen working on hiproofs it will be obvious that the scaffold brackets cannot be maintained in position as in the manner of an ordinary gable roof; and under this condition the auxiliarychains 19 would be attached to chains 15, and the chains extended around the sides of theroof to the side opposite to. that upon which the brackets are positioned andtlien engaged with the shingles or with the roof boards of said; 0) )osite side-:7 i i It will be seen that with the provisions oi scafiold brackets havhgroof connecting means of the above described character, the Y brackets may be. practically used on various types of inclined roofs and be easily adjust ed to. any desired position to meet the d fferent conditions which arise in roof building and repa ring.

The brackets are designed with the view of being collapsibleiso as to displacebut a minimum of space when be ng: sh pped or trans-o feature being clearly shown in their ends terminating at common apex,
